TV Repair Guide
A practical TV repair guide for Tabuk covering black screen, no picture, sound problems, backlight, stuck logo, HDMI, lines, restarting and safe checks.
Before You Start
A TV problem does not always mean the screen itself is damaged. The fault may come from the power supply, backlight, main board, software, HDMI connection or display panel. Start with the safe checks below before deciding on repair.
Safety first: Do not open electrical appliances, live power supplies or sealed systems unless you are qualified to do so.
01TV Has a Black Screen
Check the remote/source input, power-cycle the TV, and confirm whether sound or menu response is present. A dark screen can be related to backlight, power board, main board or panel circuitry.
Common causes
Possible causes include backlight failure, power board issues, main-board faults, display connections, or panel problems.
Safe checks
Check the input/source and whether the TV responds to the remote or shows a menu. Do not open the TV because internal power components can be dangerous.

Try another input and open the TV menu. If the menu is also invisible, the fault may involve the backlight, display connection, main board or panel.
Common causes
Possible causes include backlight failure, display connection, main-board faults, or panel circuitry.
Safe checks
Try another input and open the TV menu. If the menu is also invisible, arrange a professional diagnosis rather than opening the set.

Remove external devices and check the power connection. Repeated restarting should be inspected before continued use.

HDMI, Lines or Picture Problems
Test another HDMI cable and input where possible. Persistent lines, color faults or input failure may need internal diagnosis.

Safe checks
Try another HDMI cable and input. For persistent lines, color problems, or missing inputs, professional testing is recommended.

TV Has No Power
Check the wall socket and power connection. If there is still no response, avoid opening the TV because internal power components can remain electrically dangerous.
Common causes
Possible causes include the outlet, power board, fuse/protection, standby circuit, or main-board problems.
Safe checks
Check the wall outlet and power cable. If the TV remains completely unresponsive, do not open it or work on the power supply yourself.
